I am wondering if anyone has experiences with how different tools to generate callgraphs of binary code compare to each other in terms of speed and accuracy. Is there a superior one? I've tried radare2 and angr so far and feel like r2 is pretty slow and angr not very accurate. However, thats only a feeling after manually generating a couple CGs. Are there any papers comparing the quality of generated CGs? What would you use and why?
